Fund raiser for bus?

Is it possible that members could 3d print items and business cards for bus donation and go door to door selling 3d printed items for donation for the bus on line or a check made out to the chair of a commity? Perhaps others have better ideas on funderaser?

Hi TJ,
Here is a videos I try to follow when thinking about fundraiser for non-profit groups like ours. Often taxes are where we mess this stuff up. The video is a little over 9 minutes long and very dry, sorry about that, but it is informative.
